Title: Pile material discharge measurement method in pile driving construction method
Inventor: AKAMATSU TAKEHITO
IPC: E02D3/08
Filed: 1990-08-08
Abstract: PURPOSE:To improve accuracy in measuring a discharged pile material by detecting a sound wave emitted to a tube air column under two different conditions of an open/close plate to obtain a resonance frequency, and measuring the discharge amount of the pile material after obtaining the top position thereof. CONSTITUTION:A white noise as a sound wave is emitted toward the inside of a casing 2 from a sound generation device 34 through a speaker 33, with an open/close plate 31 kept close. Then, the resonating sound of the noise is detected with a microphone 35. The resonance frequency fC of the detected output signal is analyzed with a frequency analyzer 36 for transmission to a tube air column operation section 37. Then, the resonating sound is similarly detected, with the open/close plate 31 kept open, and the resonance frequency fO is analyzed for transmission to the tube air column operation section 37. Tube air column length l is obtained with the tube air column operation section 37 under two different conditions of the open/close plate 31, thereby calculating the top position 11 of a pile material 5.

Title: Manufacture of amalgamated zinc alloy powder
Inventor: NAKAMURA KIYONOBU
IPC: H01M4/42
Filed: 1987-08-24
Abstract: PURPOSE:To retard hydrogen gas evolution in spite of a low mercury content by atomizing a zinc alloy with high pressure gas in a specified low oxygen content atmosphere, and heating zinc powder obtained at a constant temperature, then amalgamating the zinc alloy powder. CONSTITUTION:Zinc alloy powder is prepared by atomizing a molten zinc alloy in a low oxygen concentration atmosphere. An atomizing chamber is closed and the oxygen concentration in the chamber is controlled to 4vol.% or below by using an inert gas such as argon and nitrogen. Zinc alloy powder obtained is heated at 200 deg.C which is equal to the melting point of the zinc alloy. By this heat treatment, the crystal grain of the zinc alloy grows. Then, the zinc alloy powder is amalgamated with mercury or a mercury compound. By using this amalgamated zinc alloy powder as a negative active material of an alkaline battery, hydrogen gas evolution is retarded in spite of a low amalgamation.

Title: Erasing device for reversible heat sensitive recording medium
Inventor: SONE SHOHEI
IPC: B41J2/32
Filed: 1996-08-08
Abstract: PROBLEM TO BE SOLVED: To ensure the erasure of printed characters with a simple device by providing a heat source, a feeding roller, and an opposing member opposing to the feeding roller so as to convey a reversible heat sensitive recording medium for erasing characters such that it contacts with the feeding roller and the opposing member circumferentially. SOLUTION: When driving an erasing device, a printed reversible heat sensitive recording medium 7 inserted between an upper container 3 and a lower container 2 is sent to a gap between a feeding roller 4 and the lower container 2, which serves as an opposing member. The lower container 2 is heated by a heater 1 to a predetermined erasing temperature so as to heat the reversible heat sensitive recording medium 7 to the erasing temperature before discharging. At the time, the reversible heat sensitive medium 7 contacts with the lower container 2 closely so that it can be heated to the erasing temperature to securely erase the printed characters.  Since the reversible heat sensitive recording medium 7 contacts with the lower container 2 circumferentially in a large area, the entire surface of the reversible heat sensitive recording medium 7 can be heated to the erasing temperature to securely erase the printed characters.

Title: Breeding of f1 hybrid of wheat having high yield
Inventor: MURAI KOJI
IPC: A01H5/00
Filed: 1990-08-07
Abstract: PURPOSE:To breed an F1 hybrid of wheat having high yield in high efficiency by using a wheat variety originated from new mediumlong grain variety having the number of grains per ear larger than that of wheat of SHIROGANE-variety as a parent and using a wheat variety originated from selection 14 having the number of grains per ear larger than that of TOBARI variety as the other parent. CONSTITUTION:A parent variety to form a mother stock (mother variety) is selected and the stamen of the variety is removed before pollination to prevent the pollination with own pollen. The castrated mother variety is grown by pollinating with pollen of other parent variety to form a father stock (father variety) (cross-pollination). The breeding of a high-yield variety can be easily and efficiently performed by combining a wheat variety originated from new medium-long grain variety having the number of grains per ear larger than that of wheat of SHIROGANE-variety with a wheat variety originated from selection 14 having the number of grains per ear larger than that of TOBARI variety. Yield higher than standard variety can be achieved under principally the same cultivation condition as conventional cultivation without using additional investment and labor for the improvement of the cultivation method and the pest-controlling method.

IPC: H04N5/16
Filed: 1994-09-02
Abstract: PURPOSE: To execute shading correction following the deterioration of illumination and photoelectric conversion element by leaving a fixed rate of shading correction data in a holding means by reading an original and substituting peak data in a peak holding means for other correction data. CONSTITUTION: A digital image signal 7 is inputted from an A/D conversion circuit 6 to a shading correction circuit 8. White peak hold memory 22 ignores data in a black part outputted from each picture element of a message sensor 1 by reading the original 3 in a sub scanning direction, and writes white data of maximum value, and collects the white peak data of the original 3. A data conversion circuit 34 substitutes the ratio in shading correction memory 11 by pixel data in the memory 22. When the circuit 8 is operated, white paper is read by setting a mode at an initialization mode to input white reference as the shading correction data to correction memory 1. Such data is written on the memory 11 by an initialization signal via a MUX 28. A shading arithmetic circuit 10 applies the shading correction to the data from the memory 11, and outputs a shading correction signal 9.

Abstract: PURPOSE:To obtain a desired gradation versus image density characteristic from a low up to a high density by applying laser exposure on a photoreceptor drum based on a gradation signal and developing the exposure so as to form a gradation image on the photoreceptor drum. CONSTITUTION:A gradation pattern image whose density changes continuously is formed on a photoreceptor drum based on a predetermined gradation pattern signal whose gradation changes continuously in advance (S1), the density of each part of the gradation pattern image is detected by a sensor to obtain a characteristic (gamma curve) of the image density with respect to each gradation (S2) and the result is compared with a reference gamma curve (S3). Based on the result of comparison, gradation is controlled for a high density part depending on the setting of development performance (S5), for a medium density part depending on the setting of exposure intensity (S8) and for a low density part depending on the correction of the gradation signal (S10).
